Questionable Software Patents Main Reason for Rise in Lawsuits: GAO

Misleading headline. PMEs making 19% of filings suggests they are just a part of the issue. Perhaps large companies copying software and treating the possible follow up suits as an acceptable business expense is part of the issue. Software patent suits are difficult and gaining a favorable verdict does not equate to obtaining payment from the large offender which has enough legal assets to tie things up indefinitely.
